I think we need to calm down a little, nobody is any adding any faction to the game--Geneva55 is just reviewing archeological books from the time period and keeping track of them in case we ever need them. If you want to discuss why you would potentially want or not want to have a South American civilization, go to the forum post about that. Whatever you do, please be polite. The devs have been putting a lot of work on the game, please don't make them have to stop their work and sort through a fight.
